This demonstration is a simple way to show a couple of key points :

The nodes are immediately able to communicate with each other. There is no such
thing as a “network join time” with SNAP.
Any node can talk to any other node. There is no central “coordinator” node with
SNAP.
No PC software required. There is no need for software installed on a PC to
“coordinate” the nodes, they can think for themselves.
Using SNAPpy scripts, SNAP nodes can autonomously respond to changes in
their environment. This button press could easily have come from some form of
digital or analog sensor reading.
The counting you just observed is accomplished using the multicast capabilities of
SNAP. If other modules were added to the network, they too would track the button
count and could even participate in the counting.
The first example was pretty simple. Let’s expand on things and include a look at how
nodes can interact with Synapse’s Portal software.
